CARBON ELIMINATOR AND LUBRICATOR FOR GAS-ENGINES.

Specification of Letters'Pate'nt.

Patented June 3, 1919.

Application filed November 23, 191B. Serial No. 268,893.

To all whom it may concern:

Be it known that I, EUGENE E. YoUNo, a citizen of the United States, residing at Syracuse, in the county of Onondaga and State of New York, have invented certain new and useful Improvements in Carbon- Eliminators and Lubricators for Gas-Engines, of which the following is a specification.

This invention relates to means for eliminating carbon in gas-engines, and has for its object'tb provide a novelysimp'le and effective device of the class, which collects the hot vapor or steam generated by the radiator of an automobile and conducts and discharges the same under certain regulating means into the intake manifold of the engine, where it is mixed with the explosive gas supplied by the carbureter forweake'ning the mixture, as well as for supplying the requisite moisture within the explosive chambers for preventing the accumulation of carbon therein. A further object of the invention is to provide novel and simple means for lubricating the'engine cylinders. And a further'object is to 'utilize certain parts of the main device for effecting the priming of the engine when the latter is started.

I attain these 0bjectsby the means set forth in the detailed description which follows, andas illustrated by the accompanyin drawing, in which Figure 1 is a perspective view of the front portion of an automobile, with parts broken away; showing the construction, arrangement and operation of the improvement.

Fig. 2 is an enlarged sectional view of the top of the auto-radiator; showing certain parts of the invention appliedthereto.

Fig. 3 is an enlarged sectional view of the cock which controls the flow of the steam from the radiator to the engine.

Fig. 4. is an enlarged view, partially in elevation and partially in section, showing the construction of a convenient form of needle-valve for controlling the flow of the priming mixture.

Fig. 5 is an enlarged sectional view of the butterfly valve which is automatically operated by the throttle operating mechanism.

In the drawing, 2 represents generally the gas-engine of an automobile, 3 is the radiator, on the top of which is disposed the usual filling-neck 4:, which is closed by a cap 5. 6 is a conventional representation of a carburetor, with which is associated the usual throttle, the latter being operated by a crank 7 and a rod 8, and 9 is the dash, which supports certain parts of the new mechanism.

In carrying out the objects and working of the invention, I make use of the hot vapor or steam, which is practically constantly present in the top portioirof the radiator 3, and for this purpose, I insert; one end of a pipe 10 into the top of the radiator, and mount upon the said end a nozzle 11, whose flaring mouth is preferably shielded by a gauze cap '12. The pipe 10 is preferably bent upwardly, so as to "position the nozzle 11 within the' neck 4. above and clear of the water and 'other liquid contained by the ra diator. A check-valve 13 inclosed in a tube 14 is inserted'thiough a perforation in the top of the cap 5, for providing varying quantities of oxygen to be mixed with the explosive gas under certain conditions, but prevents the water and steam from escapin through said vent. The tube 10 then extends rearwardly, preferably beneath the hood15 and passes through the dash 9, where it is attached to a cock 16,'Wlli(,i1' permits'or prevents "the passage of the steam and air from the radiator to the engine. The plug 16' of the cock may be operated manually, by the driver of the car, for gaging the volume of the steam to be supplied to the engine according to the state of the weather and other conditions, by means of a rod 17, to which is rigidly attached a pointer 18, and which is arranged to play over an indicator dial 19, the latter having upon its face certain letters and figures which indicate several positions to which the plug 16 may be romted and set. A second section of the tube, as 10' connects the cook 16 with a T 20, and a third section, as 10", extends from the T 20 through the dash 9, and thence forwardly at an incline, to a point directly over the carburetor-6, where it connects with the body of a butterfly valve 22, the said valve being supported by the intake manifold and operated by a crank 23.

The asolene for operating the engine is supplied by a tank 24, which in the'presen't case is mounted on the front side of the dash 9, beneath the hood, the gasolene being conducted by gravity to the carbureter 6 by a pipe 26. To provide novel and simple means for priming'the engine for starting the same, by utilizing certain parts of my steam injecting mechanism, I tap the supply-pipe 26, as at, 27, by a pipe 28, which connects with the T 20, and in this pipe I dispose a needlevalve, desi nated generally by the numeral 29, and whlch controls the flow of the gasolene from the pipe 26 to the pipe 10". The needle'valve 29 is operated by a rotatable rod 30, which is supported by the dash, and the said valve may be operated at will by the driver of the car, for feeding suitable charges of gasolene directly into the intake manifold 31 for priming the engine, instead of waiting for the slower and smaller feedin of the gas from the carbureter.

The butterfly valve 22 is operated by a rod 32, which is positioned substantially parallel to the throttle-operating rod 8, and these two rods are pivotally connected to the opposite ends of a rocking lever 33, which is supported by and rocks with a shaft 34 located beneath the floor 35. The lever 33 is rocked by means of a pedal-pin 36, which comprises a part of the well-known foot accelerator. The full lines in Fig. 1 show the positions of the rods 8 and 32 when the throttle 7 is open and the butterfly valve 22 is closed (see Fig. 5). The dotted lines in Fig. 1 indicate that the throttle is closed and the butterfly valve is open.

To provide in a novel and simple Way for the lubrication of the engine cylinders, I pour a suitable quantity of lubricating and kerosene oil into the top of the radiator, where it floats upon the water, as shown at 37 in Fig. 1. The high temperature of the water in the radiator tends to volatilize the oils, and their vapors are drawn off and conducted to the cylinders together with the steam, thus providing an extremely simple, practical and economic method of lubrication, which does away with the usual more or less complicated lubricating mechanisms.

The operation of my improvement is as follows: To start the engine, the throttle is usually first operated to the open position, which automatically closes the butterfly valve 22, as shown in Fig. 5. The driver then opens the needle-valve 29 for a moment to allow a charge of the gasolene contained in the tank 24 to gravitate throu h the pipe 10 to the manifold 31. The va ve 22 does not entirely close the passage through its casing, so that the gasolene filters through said valve and the first suction of the pistons draws the gas directly into the cylinders and starts the engine. As soon as the engine warms up, the cook 16 should be opened to the desired extent, which allows the hot vapor, or air at atmospheric temperature, and the lubricant to be drawn toward the cylinders. The throttle is then closed or partially closed, as usual, which operation correspondingly opens the valve 22 for the admission of the steam and lubricant into the cylinders. If the weather is warm, the

rock 16 is left open to whatever extent the conditions of the Weather and the speed of the var require. In cold weather, the cock 16 should he left closed until the engine becomes hot enough to generate the steam or hot vapor in the radiator. When the car is being driven at high speed and rich gas is required, the cock 16 should be closed sulficientl v to allow barely enough of the steam or hot vapor to pass from the radiator to the engine to prevent the accumulation of carbon in the cylinders, on the spark-plugs, and valves, and to lubricate the upper ends of the pistons. But when traveling at low speed, when less power is required, it is desirable to weaken the gas supplied by the varbureter, and this is accomplished by the driver by opening the cock 16 to a greater extent, for allowing the requisite amount of the diluting fluid or vapor to be drawn into the engine. In this way the carburetor needs no change of adjustment, and the explosive mixture supplied by it may be enriched or weakened at will, by the simple manipulation of the rod 17, which supports the indicator 18, and which is located wlthin easy reach of the driver of the car.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is l. A tube adapted to draw steam from the radiator of a gas-engine, a valve adapted to control the admission of the steam into the intake manifold of the engine, a cock con nected to said tube between the radiator and said valve adapted to age the flow of the steam through said tube independently of said valve, means for indicating the extent said cock is opened, and a rocking lever adapted to open the throttle of the engine and close said valve simultaneously.

2. The combination with the intake maniiold, the throttle, and the radiator of a gasengine, said radiator having a fresh air inlet valve, of a tube for conducting hot vapor mixed with fresh air from said radiator to said manifold, a cock and an indicator assoiated therewith for gaging the volume of the vapor passing through said tube, a butterfly valve supported by said tube between the cock and the manifold, and a rocking lever adapted to open said valve while closing the throttle, and vice versa.

4. The combination with a radiator and a gas-engine having a throttle and an intake manifold, of a pipe tapping the radiator for conducting hot vapor to said manifold, a valve supported by the manifold and connected to said pipe, a throttle operating mechanism including a rocking lever and a rod, a second rod operatively eonnevting said lever with said valve, said rods adapted to be moved in opposite directions by the rocking of said lever for simultaneously opening the throttle and for closing said valve and vice versa, and a cock for predetermining the flow of the vapor to said valve.

5. The combination with the radiator and the throttle operating mechanism of an internal combustion engine, of means for injecting hot vapor into the engine ahead of the throttle comprising a tube having one end inserted in the top of the radiator, a valve mounted above the throttle and con netted to the opposite end of said tube, means for operatively conneeting said valve with said mevhanism. whereby said valve is automatically opened When the throttle is closed and vice versa, and manually operated means interposed between said valve and the radiator for independently gaging the volume of the vapor passing through said tube.

In testimony whereof I aflix my signature.
